Waze can have giant screw-ups. I live in a valley with one major freeway. Every now and then a major accident at a choke point on the freeway will stop all traffic. Waze will then tell drivers of 2 alternate routes on surface streets. Both routes, however, re-connect to the freeway below this choke point. Now instead of just the freeway having gridlock, every thoroughfare in the valley is gridlocked and locals cannot even get out of their house or back to their house from local shopping.
